tomcat使用redis共享session并实现单点登录

下载依赖

tomcat-redis-manager https://github.com/jcoleman/tomcat-redis-session-manager/downloads

commons-pool http://commons.apache.org/proper/commons-pool/download_pool.cgi

jedis http://mvnrepository.com/artifact/redis.clients/jedis

将这几个jar包放入所有tomcat的lib中

下载并安装redis

windows https://github.com/MSOpenTech/redis/releases

linux http://download.redis.io/releases/

具体安装和配置方法见百度

修改每个tomcat的context.xml文件

<Context  sessionCookiePath="/"><!-- sessionCookiePath设置session cookie的域为根域名 -->
<WatchedResource>WEB-INF/web.xml</WatchedResource>
<Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" />
<Manager className="com.orangefunction.tomcat.redissessions.RedisSessionManager"
host="localhost"
port="6379"
database="0"
maxInactiveInterval="60"
password="这里写redis的密码（如果有）"/>
</Context>

配置完毕,启动tomcat

注意：要放入session中的类要实现序列化接口，序列号相同
